Vaccination coverage declined from 54.2% to 36.4%, while the proportion of susceptible dogs rose from 8.7% to 29.5%. The CPV nucleic acid positive rate in dogs was 3.9% (4\/102, all sub-adults, three deaths), whereas all giant panda samples were negative. Based on individual\u2013seasonal exposure, the serum exposure rate was 30.4%, with immature dogs at significantly higher risk than adults (OR = 5.37). Home-range overlap between dogs and giant pandas (95% KDE: 19.17% in cold seasons vs. 2.61% in warm seasons) and encounter probability were markedly higher in winter and spring. Canine-derived CPV strains possessed the molecular potential to infect giant pandas. In summary, CPV persists long-term in free-roaming dog populations, summer vaccination has not established an effective immune barrier, and winter\u2013spring is a high-risk window for cross-species transmission. We recommend enhanced winter\u2013spring immunization, spatial control measures, and quarantine protocols for incoming dogs.<\/jats:p>","DOI":"10.3390\/ani16111686","type":"journal-article","created":{"date-parts":[[2026,6,1]],"date-time":"2026-06-01T08:09:16Z","timestamp":1780301356000},"page":"1686","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Surveillance of Parvovirus in Free-Roaming Dogs in the Qinling Mountains and Assessment of the Risk of Cross-Species Transmission to Giant Pandas"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-4032-300X","authenticated-orcid":false,"given":"Zhiyang","family":"Huang","sequence":"first","affiliation":[{"name":"College of Veterinary Medicine, China Agricultural University, Beijing 100193, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"U","family":"Cheong","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, China Agricultural University, Beijing 100193, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0807-9801","authenticated-orcid":false,"given":"Zichen","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, China Agricultural University, Beijing 100193, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiao","family":"He","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, China Agricultural University, Beijing 100193, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leigang","family":"Zhao","sequence":"additional","affiliation":[{"name":"Foping National Nature Reserve Administration, Foping County, Hanzhong 723400, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dapeng","family":"Zhu","sequence":"additional","affiliation":[{"name":"Foping National Nature Reserve Administration, Foping County, Hanzhong 723400, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haojie","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, China Agricultural University, Beijing 100193, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuhan","family":"Tsai","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, China Agricultural University, Beijing 100193, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingjie","family":"Wei","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, China Agricultural University, Beijing 100193, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhonghao","family":"Dan","sequence":"additional","affiliation":[{"name":"Foping National Nature Reserve Administration, Foping County, Hanzhong 723400, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bolong","family":"Lu","sequence":"additional","affiliation":[{"name":"Foping National Nature Reserve Administration, Foping County, Hanzhong 723400, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5244-8358","authenticated-orcid":false,"given":"Yipeng","family":"Jin","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, China Agricultural University, Beijing 100193, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11266","DOI":"10.1038\/s41598-019-47773-6","article-title":"Canine parvovirus (CPV) phylogeny is associated with disease severity","volume":"9","author":"Franzo","year":"2019","journal-title":"Sci.
